That's so interesting. Can you give us more details or a technical website where this is discussed? All the scripts I've ever read give little or no information about camera angles, lighting, or actor movements. They focus on dialogue, situation, and conflicts. Anything else is taking away power from the director to make the blocking, set-up, and shot choices later on in the production, using storyboards and mockup shots.

As others have said here, it's more likely that movies made today (including possibly The Hobbit) will be exhibited in both 2D and 3D formats, and that would seem to dictate leaving the shots up to the director, not locking them into the script. A script written the way you say, especially for 3D, might not be such a great basis for a 2D version!
